name	geopandas-projection-tools
description	Handles CRS transformations and distance calculations in kilometers. Use this for converting between geographic coordinates (WGS84) and equal-area projections (like Lambert Azimuthal Equal Area centered on the Pacific region) for accurate distance measurements.

CRS Transformation

For accurate distance measurement in km, always transform to an appropriate local projected coordinate system (e.g., EPSG:6933 for equal-area or custom projections centered on the region of interest).

Distance Calculation

1. Set the GeoDataFrame CRS to EPSG:4326.
2. Reproject to a meters-based projection (e.g., EPSG:3857 for simplicity or a custom equal-area projection for scientific accuracy).
3. Use .distance() to calculate distances.
4. Convert result to km (divide by 1000).
